Have you crossed a roundabout by foot? The crosswalk is offset from the border of the road by like 5 meters, meaning it takes like twice as much to cross. The crosswalk is also not in the slowest part of the roundabout.

This intersection forces drivers to slow down by having floating islands that narrow the lanes and force tighter turning radii. Drivers going straight through interact with pedestrians and cyclists less than drivers who are turning because this is a signaled intersection.
